Sound cards, sound cards, sound cards. The Guilmot is a good card ($300), and because I'm mastering to CD within the computer, I don't need a lot of in/outs. There are better ones out there for sure, but not in the same price range. I haven't quite decided on the best software to use, however in the long run it's all about what you feel most comfortable with. One final note: This studio was cheap for the quality of sound I can get. The total for the above equipment was only about $3000 (Not including the instruments).
